Objectives: It is our clinical observation that patients with transformed migraine (TM) almost invariably report nonrestorative sleep. In this study we sought first to validate that clinical observation, then to describe the prevalence and spectrum of factors that might contribute to nonrestorative sleep in a TM population.
Background: Although headaches have been linked with sleep problems for over a century, there is little information about the spectrum or prevalence of specific sleep problems associated with TM in adults.
